Domestic Flight Haneda to Sapporo

Hi..
I wonder anyone know or maybe have an experience transiting in Haneda for Sapporo or maybe Domestic flight?

Will flight from Indonesia to Tokyo(Haneda) for transit to Sapporo, flying with ANA.

My questions are:
1. I only have 2 hours transit in Haneda, and how if the traffic at the immigration took so long? I never been to Haneda before, because at Narita i ever stuck for -+1 hour just for immigration check.

2. I will arrive at International Airport, so i must change to Domestic terminal, and how about the baggage? we should take it and bring with us or they will arrange it for us?

3. What should i take to go to Domestic Terminal?

4. If i need assistant due this transfer, is it easy to looking for ANA assistant?

5. Is 2 hours transit is enough? (immigration check, waiting for baggage, custom declare, way to Domestic terminal)


hope you could help me since i really worry and cannot imagine how to transfer for Domestic flight especially for the baggage system...

thanks in advance!:)

There is no problem unless there is a serious delay in the airplane.

Procedures, baggage, how to move airport can be confirmed at ANA and HND web sites.

In HND It is normal to set "2 hrs(120 mins)" for international flight to domestic flight transfer.
Transfer ANA to ANA at HND decided to be over 80 mins.
https://www.ana.co.jp/en/jp/domestic/prepare/checkin/transit.html
-- Immigration : 30 to 60 mins
-- Terminal movement: 20 - 30 mins (free shuttle bus or train [charged])
-- Domestic flight check-in deadline : 20 mins before of dep time

Are the flights all on one ticket? If so, then if the international arrival is delayed, the airline will put you on the next available flight to CTS.
Do not waste your time after deplaning but instead try and get to immigration ASAP.
After immigration, pick up luggage then customs. On exit turn right, ANA checkin counters are located there.
Therefs free shuttle to the domestic terminal.
Just ask if not sure as the ANA staff are both helpful and friendly.

At the domestic terminal youfll have to go through security so make sure you allow plenty of time.
There are several places to buy food and drinks airside, so you donft need to buy them before security. Prices are all the same - no price gouging.
